Что такое Microsoft Kernel Debug Network Adapter и можно ли его отключить
Изучая список доступных устройств в диспетчере устройств, вы можете обратить внимание на наличие пункта «Microsoft Kernel Debug Network Adapter» в разделе «Сетевые адаптеры». Обычно устройство отображается лишь в случае, если отметить опцию «Показать скрытые устройства» в меню «Вид», но иногда видно и без этого действия.
В этой статье о том, что такое Microsoft Kernel Debug Network Adapter (или «Сетевой адаптер с отладкой ядра») в Windows 11, Windows 10 и других версиях системы, для чего нужен, следует ли и можно ли предпринимать какие-либо действия в отношении этого сетевого адаптера.
Назначение Microsoft Kernel Debug Network Adapter
Microsoft Kernel Debug Network Adapter (Сетевой адаптер с отладкой ядра) — виртуальный сетевой адаптер, предназначенный для удаленной отладки Windows по сети.
В ранних версиях Windows отладка проводилась через последовательный порт, USB или Firewire, а начиная с Windows Server 2012 и заканчивая актуальными версиями Windows 11 и Windows 10 стала доступна и отладка по сети, где и используется рассматриваемое виртуальное сетевое устройство.
Для рядового пользователя на домашнем компьютере или ноутбуке обычно будут одновременно верны следующие два утверждения:
- Никакого применения для Microsoft Kernel Debug Network Adapter в вашем случае нет.
- Никакого вреда от наличия этого устройства также нет — ни для работы, ни производительности системы.
Можно ли удалить или отключить Microsoft Kernel Debug Network Adapter
Да, вы можете отключить Microsoft Kernel Debug Network Adapter просто нажав по нему правой кнопкой мыши в диспетчере устройств и выбрав пункт «Отключить устройство»:
Это не должно привести к каким-либо проблемам с работой сети или Интернета. Однако, есть редкие отзывы, где такие проблемы возникают. Поэтому я не рекомендую удалять его, во всяком случае пока не убедитесь, что после отключения сетевого адаптера всё работает исправно.
Среди прочих советов, позволяющих убрать Microsoft Kernel Debug Network Adapter из диспетчера устройств, можно встретить рекомендацию отключить возможность отладки Windows:
- Запустите командную строку от имени администратора.
- Введите командуи нажмите Enter.
- Закройте командную строку и перезагрузите компьютер.
По этому поводу могу отметить, что:
- Эти действия не убирают устройство в актуальных версиях Windows.
- Отладка и без того обычно отключена на компьютерах пользователей. Посмотреть её статус можно с помощью команды bcdedit /enum в командной строке. Если в разделе «Загрузка Windows» отсутствует пункт «debug» или для него установлено значение «No», это говорит об отключенной отладке.
На этом завершаю. Если у вас остаются дополнительные вопросы по рассмотренной теме, жду их в комментариях ниже.

The /debug boot option enables or disables kernel debugging of the Windows operating system associated with the specified boot entry or the current boot entry.
[!CAUTION] Administrative privileges are required to use BCDEdit to modify BCD. Changing some boot entry options using the BCDEdit command could render your computer inoperable. As an alternative, use the Startup settings in Windows.
[!NOTE] Before setting BCDEdit options you might need to disable or suspend BitLocker and Secure Boot on the computer.
The <ID> is the ID that is associated with the boot entry, such as
on
Enables kernel debugging of the specified boot entry. If a boot entry is not specified, kernel debugging is enabled for the current operating system.
off
Disables kernel debugger of the specified boot entry. If a boot entry is not specified, kernel debugging is disabled for the current operating system.
The /debug boot option enables kernel debugging for a specific boot entry. Use the /dbgsettings option to configure the type of debugging connection to use and the connection parameters. If no /dbgsettings are specified for the boot entry, the global debug settings are used. The default values for the global settings are shown in the following table.
| dbgsetting parameter | Default value |
|---|---|
| debugtype | Local |
| debugstart | Active |
| noumex | Yes |
The following example enables kernel debugging of the default boot entry.
To check the current debugging parameter values, use the BCDEdit /dbgsettings command as shown here.
MS-DOS and Windows command line bcdedit command
The bcdedit command line tool modifies the boot configuration data store, contains configuration parameters and controls how the operating system is booted. These parameters were previously in the boot.ini file (in BIOS-based operating systems) or in the nonvolatile RAM entries (in EFI (Extensible Firmware Interface-based) operating systems). You can use Bcdedit.exe to add, delete, edit, and append entries in the boot configuration data store.
Availability
Bcdedit is an external command that is available for the following Microsoft operating systems as bcdedit.exe.
Bcdedit syntax
To use the bcdedit command, you must be in an elevated command prompt.
Running "bcdedit" by itself is equivalent to running "bcdedit /enum ACTIVE".

While experimenting with my Windows 7 computer I installed some application and it enabled debugging mode and put a water mark on the screen saying “test mode” along with OS name and version number. The debugging mode option was displayed at the boot selector menu while starting the computer , otherwise this setting is not very evident.
If you want to confirm that these settings are enabled or not in your computer, type the command bcdedit from an elevated (Run as administrator) command prompt and read through the output on the screen.
Following are the commands to disable debugging mode
bcdedit /debug OFF
To disable debugging for another OS instance in the same computer type the following commands
bcdedit /debug {GUID} OFF.
GUID can also be found from the output of bcdedit command
Here is the command to remove the “test mode” water mark from your screen
